Just completed story mode on Normal, overall I have done 65% complete. I bought all skills, but haven't bought all weapon upgrades (I still need most of the weapon parts you find through out the world) Although at least I have fully upgraded the shotty (imo the best weapon) so you can blow enemies away with ease. All the other collectibles like relics and stuff I haven't found much of as I just focused on finishing the story. Download here: http://www.mediafire.com/download.php?zyd899sa3rs8btr Enjoy.
